RunAsync 中的生成 actors 抛出 "Interface id '1830616258' is not implemented by object 'CustomActorService.InternalCustomActorService'"

Question

我正在按照 中的建议在服务启动时生成几个参与者。我有一个带有以下 RunAsync 覆盖的自定义 ActorService subclass：

internal sealed class InternalCustomActorService : ActorService
{
  protected async override Task RunAsync(CancellationToken cancellationToken)
  {
    await base.RunAsync(cancellationToken);

    for(int i = 0; i < 10; i++)
    {
      ICustomActor proxy = ActorProxy.Create<ICustomActor>(new ActorId(i));
      await proxy.StartAsync();
    }
  }
...

class在Program.cs中注册如下：

    ActorRuntime.RegisterActorAsync<CustomActor>(
       (context, actorType) => new InternalCustomActorService(context, actorType, () => new CustomActor())).GetAwaiter().GetResult();

但是，我在调用 proxy.StartAsync() 方法时遇到以下异常：

FatalExecutionEngineError occurred
  HResult=-2146233088
  Message=One or more errors occurred.

我的问题是：我做错了什么？

编辑：我尝试添加额外的 BootstrapperService 无状态服务并从那里生成演员 BootstrapperService.RunAsync:

protected override async Task RunAsync(CancellationToken cancellationToken)
{
  await base.RunAsync(cancellationToken);
  await Task.Delay(10000);

  for (int i = 0; i < 10; i++)
  {
    ICustomActor proxy = ActorProxy.Create<ICustomActor>(new ActorId(i));
    await proxy.StartAsync();
  }
}

然而，对 proxy.StartAsync() 的调用抛出与上述 InternalCustomActorService.RunAsync 中完全相同的异常。

Answer 1

从您的自定义 actor 服务中删除以下代码：

     protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners() 
 { 
   var remotingListener = new ServiceReplicaListener(context => this.CreateServiceRemotingListener(context)); 
   return new ServiceReplicaListener[] { remotingListener }; 
 } 

这将删除基础 ActorService 正在设置的 ActorRemotingListener。如果您想添加额外的侦听器，请调用基本的 CreateServiceReplicaListeners 方法，获取侦听器，然后添加自定义侦听器。
